Prepare the loaf pan by taking some butter and spreading enough in the pan to leave behind a thin layer of butter. I usually like to take a smidge of butter left in the fridge to do this, and use my hands afterwards to thoroughly spread it all over the inside of the pan. Place a spoonful of flour in the pan, and pat the pan while turning it in order to have the flour evenly coat the butter layer. Once done, turn the pan upside down over the trash can or sink, and heavily pat the bottom of the pan to discard the excess flour.
Mix the dry ingredients together in a small bowl (flour, baking powder, baking soda, and salt). You'll be pouring this into the big mixing bowl. Push this bowl off to the side now.
Mush the bananas ((I used my hands to to this) in another bowl of the same size used for the dry ingredients, and add in the milk and cinnamon to the bananas. Mix it up, and put to the side.
In a large mixing bowl, we're going to mix the sugar and butter together using the Cuisinart Smartstick with the whisk attachment. Once the sugar and butter have been mixed, mix in one egg at a time. After all the eggs have been added and mixed, add the banana mixture and mix again.
Once that's completed, pour in a little of the flour mixture at a time and mix. Repeat this until all of the flour mixture has been added and thoroughly mixed.
Set the oven to 325°F.
Mix the chocolate chips in until it's evenly spread throughout the batter. If you opted for walnuts to be in your chocolate chip banana bread, this is when you would mix it in.
Pour the mixture into the prepared loaf pan, then place into the oven. Bake for 70 minutes, or when you pass the "clean toothpick test." The "clean toothpick test" is when you poke the middle of the loaf with a knife or toothpick (I use a knife) all the way to the bottom, it'll come out clean if it's cooked all the way through. If any batter is on it (don't worry about the chocolate), you have to keep baking it.
Once it's done baking, let it sit for a minimum of 10 minutes to allow the cake to cool. Then take a dinner knife and gently run it along all the edges of the cake so as to separate it from the loaf pan. Turn the pan upside down over a cutting board, and roughly pat the bottom of the pan until the cake comes out of the pan and onto the cutting board.
Cut that bad boy/girl/thingymajig into some thick slices. Enjoy with a glass of milk for breakfast or dessert. Or both. No judgements here.
